You can obtain the names of all the map tiles from `leaflet::providers` [This website](http://leaflet-extras.github.io/leaflet-providers/preview/index.html) allows you to compare the map tiles. --- # {leaflet} background color The `{leaflet.extras}` package add lots of additional functionality to `{leaflet}` - including setting a background color. ```r leaflet_map %>% setMapWidgetStyle(list(background= "lightblue")) ``` --- ## Using columns in {leaflet} In `{ggplot2}` we used `aes()` to create mappings between our data and the chart. In `{leaflet}` we use `~column_name` ---
